There is a broad spectrum of sleep disturbances observed in Parkinson's disease (PD). The prevalence of symptoms of insomnia and chronic inability to sleep and their association with other sleep disorders were studied. Altogether 1447 randomly selected Parkinson patients, aged 43-89 years, participated in a questionnaire study. A structured questionnaire(More)
BACKGROUND/AIMS The objective of this study was to assess the prevalence of restless legs syndrome (RLS) in patients with myasthenia gravis (MG). METHODS We interviewed 73 MG patients and 65 healthy controls by using a structured diagnostic questionnaire based on the International Restless Legs Syndrome Study Group diagnostic criteria. We also collected(More)
OBJECTIVE Various sleep-related symptoms occur in Parkinson's disease (PD). Their occurrence with health-related quality of life (HRQL), comorbid sleep disorders, and other comorbidities was studied. METHODS Altogether, 1447 randomly selected patients with Parkinson's disease, aged 43-89 years, participated in a questionnaire study. A structured(More)
BACKGROUND Implantable intrathecal drug delivery systems (IDDS) are basic tool enabling chronic intrathecal pharmacotherapy. Lack of expected clinical results of IDDS therapy necessitates search for the cause with the help of diagnostic imaging methods among other things. Beside radiological techniques, it is also possible to visually assess IDDS systems by(More)
PURPOSE Restless legs syndrome (RLS) is a frequent sensorimotor disorder characterized by an urge to move the legs, with symptoms appearing during the night and disturbing nocturnal sleep. There is a growing body of evidence that RLS correlates with an increased risk of cardiovascular diseases and hypertension. The aim of this study was to test the(More)
Narcolepsy with cataplexy (NC) is a neurological sleep disorder characterized by very low or undetectable concentration of hypocretin-1 in the cerebrospinal fluid. It has been recently found that patients with NC have disturbed circadian pattern of blood pressure, with more frequent non-dipping, compared to healthy controls. It has been hypothesized that(More)
The contemporary use of interictal scalp electroencephalography (EEG) in the context of focal epilepsy workup relies on the visual identification of interictal epileptiform discharges. The high-specificity performance of this marker comes, however, at a cost of only moderate sensitivity. Zero-crossing interval analysis is an alternative to Fourier analysis(More)
PURPOSE Periodic limb movements in sleep (PLMS) are related to arousal, sympathetic activation, and increases in blood pressure (BP), but whether they are part of the arousal process or causative of it is unclear. Our objective was to assess the temporal distribution of arousal-related measures around PLMS. METHODS Polysomnographic recordings of six(More)
